GAS-BURN ER FOR STOVES AND FIRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 415,418, dated November 19, 1889.

Application filed August 19, 1889. Serial No. 321,270. (No model) To all whom it may concern:

Be itknown that I, TERRENCE MOSWEENEY, a citizen of the United States, residing at Allegheny,in the county of Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Gas-Burners for Stoves and Fire-Places, of which improvement. the following is a specification.

My present invention is an improvement upon that for which Letters Patent of the United States No. 406,225) were granted and issued to me under date of July 2, 1889, and its object is to effect a simplification and economy of construction and a reduction of the dimensions of the appliance, as well as to provide improved facilities for the conduction and distribution of the gas to the several series of burner-openings.

To this end my invention, generally stated, consists in the combination of a vertical supporting-plate provided on its front with a series of transverse gas-channels and 011 its back with a gas-supply passage communicating with each of said channels, a perforated cap-plate closing the top of each of said channels, and a series of retarding and radiating frames, each located above one of said channels.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a vertical central section in perspective through a gas-burning appliance embodying myinvention, all the retarding and radiating frames except the two upper ones being removed to show the construction more clearly; Fig. 2, a horizontal section through the same, the left-hand half being taken at the lineoc 5c of Fig. 1 and the right-hand half at the line 1/ y thereof; Fig. 3, a view in elevation and on an enlarged scale of a portion of one of the retarding and radiating frames, and Fig. 41 a transverse section through the same at the line 2 z of Fig.

I11 the practice of my invention I provide a supporting-plate 1 of cast metal, the height and width of which are such as to admit of being fitted in a fire-place of the class of those in which grates for solid fuel are ordinarily employed and set upon bricks or other suitable stands therein. A series of transverse gas-channels 2, of segmental or trough section, is located upon the front of the plate 1, said channels being preferably, as shown, cast integral therewith and extending from one of its sides to the other. The plate 1 is also, by preference, provided at each side with a lateral plate 3, extending forwardly for a short distance beyond the front of the gas-channels and closing the ends thereof, said lateral plates being desirable where the side jambs ,of the fire-place are irregular or at so great a distance apart that it is not necessary to employ a supporting-plate of the full width of the fire-place in order to evolve the amount of heat required, and also as affording convenient support for the retarding and radiating frames, to be presently described. It will be obvious, however, that by making the plate 1 sufficiently wide to fit at its sides against the side jambs the lateral plates 3 may be dispensed with, the ends of the gas-channel 2 being in such case closed by transverse plates cast therewith.

A vertical gas-supply passage 4,0f graduallyincreasing transverse sectional area from its top to its bottom, is fixed centrally upon the back of the supporting-plate 1, said passage communicating by supply-openings 5 with each of the gas-channels 2, and a mixer-pipe 6, adjacent to the open lower end of which is located a gas-supply nozzle 7, is connected to the bottom of the passage 4. The nozzle 7 is connected to a suitable gas-service pipe controlled in the usual manner by a cook or valve. The gas-channels 2 are each closed at top by a burner-plate 8, which is perforated with a series of burner-openings 9, the burner-plates being preferably formed separately from the plate and gas-channels and fitted thereon, in order to facilitate the formation of the cast ing, as well as to admit of the ready removal of a plate or plates when burned out. Air to support the combustion of the gas at the burners is supplied through a series of airopenings 10, formed in the plate 1 between the several gas-channels.

For the purpose, as in my patent, No. 406,229, aforesaid of retarding the products of combustion in their passage to the chimneyflue, as well as of providing an extended area of heat-radiating surface, I locate above the cap or burner-plate 8 of each of the gaschannels 2 a retarding and radiating frame 11 of skeleton or open-Work form, which frames are downwardly and forwardly inclined from the front of the supporting-plate 1, and rest at their ends on suitable supports, as lugs or projections 12 on the side plates 3, or the side jambs of the fire-place, as the case may be. I have found in practice that the retarding and radiating plates formerly employed, which were of substantially uniform thickness and so perforated as to leave a comparatively large body of metal between the openings, were objectionable on account of their tendency to be Warped and distorted by the action of the heat of the jets of flame projected upon them from the burner-openings. The retarding and radiating frames of my present invention, which are clearly shown in Figs. 3 and 4, are so formed as to obviate this objection Without impairing the function of the plates. Each frame is composed of a longitudinal upper bar a, a lower bar I), of substantially greater transverse sectional area, a series of transverse bars 0, connecting the bars a and b, and a series of arms d, projecting from the bars a, b, and c and unconnee-ted at their outer ends. An opening e is formed in each of the transverse bars 0, said openings lightening the bars 0 and preventing the undue concentration of heat thereon.

The form and arrangement of the bars and arms are such as to enable the frames to present an ornamental design for the front of the appliance inaddition to the performance of their prime function of retardation and ra diation.

It will be seen that my improvement effects a considerable reduction in cost of construction and enables the principle of my prior invention to be applied Within a smaller compass With a reduction of the number of separate and connected parts and a distribution of the gas directly to the several channels without the interposition of a chamber of any considerable volume.

Iclaim as my invention and desire to secure by Letters Patent 1. The combination of a vertical supporting-plate, a series of transverse gas-channels fixed upon and directly adjoining the front of said plate and provided With burner-openings, a gas-supply passage fixed to and extending partially across the back of said plate and communicating with each of said channels, and a series of transverse retarding and radiating frames, each located adjacent to the front of the supporting-plate and above one of the gas-channels,substantially as set forth.

2. The combination of a vertical supporting plate, a series of gas-channels of segmental section cast upon the front of said plate, a perforated burner-plate fitting over and closing the top of each of said channels, a vertical gas-supply passage of graduallyincreasing transverse sectional area from top to bottom fixed centrally to the back of the supporting= plate and communicating with each of said channels, and a series of transverse retarding and radiating frames, each located adjacent to the front of the supporting-plate and above one of the gas-channels,

substantially as set forth.

3. The combination of a vertical supporting-plate, a series of gas-channels of segmental section cast upon the front of said plate, lateral plates extending forwardly from the sides of said plate and closing the ends of I TERRENCE MOSWEENEY.
